Description

Multi-angle shock-absorbing bumper

technical field

The utility model relates to a vehicle insurance device, in particular to a multi-angle shock-absorbing bumper. the

Background technique

At present, most of the existing car bumpers in the market are mainly rigid. When a collision occurs, the impact force on the body is still very large, and in different directions, even if it hits the bumper, due to the uneven force on the bumper, The damage is serious, and the vehicle and personal safety cannot be protected from multiple directions and angles. the

Contents of the invention

In order to overcome the above problems, the utility model provides a new type of automobile bumper. The automobile bumper has a flexible damping effect. When a large impact occurs, the impact time can be prolonged and the force on the vehicle body can be reduced. Because the spring is compressed under force, the force on the bumper is uniform everywhere, reducing the stress concentration and protecting the vehicle from multiple directions and angles. the

The technical solution adopted by the utility model is: change the traditional rigid link into a spring link, the bumper mainly includes a bumper body, a shock absorbing slide bar, a horizontal slideway, a fixing frame, a pin, a longitudinal shock absorbing compression spring, a transverse shock absorbing Shock tension spring and other main components. The fixed frame is fixed on the vehicle body, one end of the longitudinal shock-absorbing compression spring is fixedly connected with the fixed frame, and the other end is fixedly connected with the transverse slideway, and the shock-absorbing slide bar I and the shock-absorbing slide bar II are jointly hinged on the fixed frame through pins. The other end of the shock-absorbing slide bar I can slide freely on the left slideway, the other end of the shock-absorbing slide bar II can slide freely on the horizontal slideway, and the longitudinal shock-absorbing structure can buffer the force in the front direction. One end of the transverse damping tension spring is linked with the damping slide bar I, and the other end is linked with the damping slide bar II. The horizontal slideway, right slideway, and left slideway are fixedly connected with the main body of the bumper. The horizontal shock-absorbing structure can buffer the lateral force. The combination of the horizontal and vertical buffer structures forms a complete multi-angle shock-absorbing bumper. The main body is the main body that bears the impact force. the

Calculate and design the maximum impact force, obtain the spring deformation coefficient according to the spring deformation limit, and reduce the impact force within the effective compression distance. the

The beneficial effect of the utility model is that the impact force of the car body can be reduced within the effective compression distance, obtained by the momentum theorem I=Ft, and the impact force can be reduced by prolonging the buffer time. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Fig. 1 is the overall structure diagram of the utility model. the

In Fig. 1: bumper main body (1), shock-absorbing slide bar I (2), horizontal slideway (3), shock-absorbing slide bar II (4), right slideway (5), fixing frame (6), pin (7), longitudinal shock-absorbing compression spring (8), transverse shock-absorbing extension spring (9), left slideway (10). the

Detailed ways

In Fig. 1, the fixed frame (6) is connected with the car body, one end of the longitudinal damping compression spring (8) is fixedly connected with the fixed frame (6), and the other end is fixedly connected with the transverse slideway (3). And the damping slide bar I (2) and the damping slide bar II (4) are hinged on the fixed frame (6) through the pin (7). The other end of the damping slide bar I (2) can slide freely on the left slideway (10), and the other end of the damping slide bar II (4) can slide freely on the horizontal slideway (3). One end of the transverse damping tension spring (9) is linked with the damping slide bar I (2), and the other end is linked with the damping slide bar II (4). The horizontal slideway (3), the right slideway (5), the left slideway (10) are fixedly connected with the bumper main body (1). The above shock-absorbing mechanisms are evenly arranged in 3 groups on the fixed mount (6), forming a complete multi-angle shock-absorbing bumper, and the bumper main body (1) is the main body that bears the impact force. the
